To all whom t may concern.-

Be it known that I, JOSEPH B. UNDERwooD,

' a citizen of the United States, residing at Fayetteville, in the county of Cumberland and State of North Carolina, have invented certain new and useful Improvements in Cigarette-Machines; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a cigarette-machine in which the tobacco stock is fed and distributed by carding-cylinders and connecting devices so as to form a ring or circle of loose stock in a circular channel at the bottom of the carding-cylinder and of approximately the required bulk or thicknessA in cross-section to form the continuous rod or filler, which ring of stock is then formed into a continuous compact filler-rod by means of a revolving anged grooved forming-disk and a grooved compressing-Wheel and continuously fed forward upon the traveling paper or other wrapper and carrying-belt, in which wrapper it is folded, one edge thereof being supplied with paste and then the wrapper sealed around the filler-rod, which rod, as it continuously travels forward, is cut into short lengths to form cigarettes, all as fully hereinafter described.

My improved machine is very much simplitied in construction and operation as compared with other continuous filler 7 cigarette machines, and my devices for feeding and distributing the tobacco-stock and forming it into a filler-rod of uniform density are especially simple in construction and effective in operation. Such feeding, distributing, and forming devices are important features of myinvention.

My machine also comprises other main features of construction, such as a compound belt composed of a strong thick driving-belt and a comparatively light thin filler-carrying belt connected longitudinally to the drivingbelt and arranged to travel in the slotted guide-trough or folding-channel; also, a pair of extractors or stripper-guides arranged on each side of the guide trough and having pointed curved ends projecting tangentially into the grooves of the forming and compresslength broken away.

plan view thereof.

ing cutting mechanism provided with a revolving and vibrating disk or blade for moving with the continuous cigaretterod and cutting it into cigarette lengths without bending or defiecting the rod during the cutting operation.

My improved machine also embraces certain details of construction by which a more perfectly-operating machine is produced, as will be hereinafter more fully pointed out in connection with the drawings.

The parts and combination of parts constituting my invention will be deined in the claims.

My machine is illustrated in the accompanying drawings, in Which- Figure l represents a left-hand side elevation of the machine with a portion of the Fig. 2 represents a top Fig. 3 lrepresents a plan view of the slotted guide-trough or foldingchannel, showing the devices for curving the belt and folding the wrapper around the fillerrod.

In my machine the important operation of feeding the tobacco-stock, distributing it in to a loose circular roll, and forming and compressing such roll into a compact continuous rod or filler, ready to be wrapped with paper or other covering, are all performed with ease and accuracy in my combined feeding and carding cylinders l and (i, and the completed filler-rod is delivered by revolving, forming, and compressing disks 12 and 39, operating at the bottom of such cylinders directly upon the traveling wrapper 52 and carrienbelt 11G, Figs. 1 and 2, arranged below in the slotted folding trough or channel 45. In this folding-channel the iiller-carrying belt and the wrapper applied tothe top surface of such belt are gradually curved into a U shape in cross-section, and at a suitable point the belt is curved over, together with the wrapper, by a deiiector 59 upon one side of the channel, while paste is applied by a wheel GO to the standing edge of the paper. Then in an advanced position the belt is separated from the turned-over edge of the paper by a separator 80, while the turned-over edge of the paper is held down upon the tobacco-rod by said separator. Then in amore advanced position the other edge of the belt and paper to which paste has been applied are turned down by a belt-curver S2, so as to seal the pasted edge of the paper upon the previously turneddown edge, and thus inelose the ller. The

completed cigarette-rod after having been inclosed in a sealed wrapper is traversed forward and continuously cut into cigarette lengths by a longitudinal reciprocating cutting mechanism provided with a vibrating revolving cutter-disk 96 at the rear end of the machine. l

The workingdevices and mechanism of the machine are suitably mounted and supported upon the tableT and frame 7, supported by the legs Y. The table is composed of two side bars or plates T T,connected by a number of web-bars t, providing a space between them for the passage of the traveling powerbelt connected with the filler and wrapper carrying belt and for a longitudinal supportingbed or guide-bar for the powerbelt.

Devices for feeding the tobacco-stock, dis tributing it into loose circular roll,and forming and compressing it into a iiller-rod will Vfirst be described as follows:

The external earding cylinder or drum 1 is mounted upon a base-plate 3 and secured thereto by the standards a, said `cylinder being supported at a sufficient height from the base-plate to admit of the band or ring 2, which, as shown, is a plain metallic band without any carding-teeth. Such band 2, in con nection with the carding-cylinder, thebaseplate 3,and the disk l2,formsacircular channel C, into which is distributed the tobacco, forming a circular loose roll of stock, from which the ller-rod is formed. The base-plate is provided with a downwarally-extending Vhub el, which is secured by a screw to the ver tical hollow bearing 5, connected by a side bracket to the frame of the lnachine. This bracket 5 not only supports the feeding and carding cylinders, but also serves as a bearing for Athe vertical shafts of the inner cardingcylinder and the inner distributing-disk.

The inner cardingcylinder 6 is slightly tapered from its base upward and is provided eentrallywith a bushing 7, through which one or 'more set-screws are inserted for securing it to the inner vertical shaft 8, which shaft is supported below in bearings formed in the bracket- arms 9 and 10, projecting from the frame or legs of the machine7 and it rests at its lower end upon an adjusting-screw 1l. The flanged grooved distributing and forming disk l2, arranged in the bottom of the outer earding-eylinder, is secured by means of a downwardly-projecting hub 13 and a setscrew to the hollow shaft 14, which is journaled in the bearing 5 and rests at its lower end upon the beveled pinion 15, which is secured to the inner shaft 8, just above the bracket 9. A large beveled gear-wheel 16 is secured to the lower end of shaft 14c and the two beveled wheels 15 and 16, Figs. l and 4, mesh with the two beveled wheels 17 and 18, fixed upon short sleeve-shaft 19, mounted loosely upon the revolving shaft 2l. A sliding clutch 2O is connected by a spline joint or feather with the shaft 21 and is operated by a lever 20a to engage with the short sleeveshaft 19 for throwing the gear-wheels 17 and IOO IIO

18 into and out of connection with the gearwheels 15 and 16. The'shaft 21 is journaled at its front end in the bracket-arm 9 and at its rear end in a box c on leg Y, and isv also provided at its rear end with a toothed gearl wheel 22, which meshes with a toothed pinion 24, iixed upon the main driving-shaft 23, which shaft is supported in journals at l) b and is provided with fast and loose pulleys 25.

The outer cylinder 1 is provided internally with a lining of card-clothing 2G, having the usual fine teeth. The inner carding-cylinder is slightly tapered from below upward and is formed with four large quarter-turn spiral grooves 27, starting in its upper surface and running out in its periphery, as indicated in Figs. 2, 4, and 6. Said grooves extend spirally downward, as shown in Fig. 4, and aid materially in feeding the tobacco down into the annular space between the inner and outer carding-cylinders. The peripheral surface of the carding-cylinder 6 outside of the spiral grooves is covered with a jacket of card-clothing 2S, which is provided along the margin of the spiral groove with one or more rows of comparatively long teeth 29. Cylinder 6 is also provided at the bottom with a circular row of long teeth 30, curved slightly downward and backward and projecting downward into the circular channel C, as shown in Figs. 4 and 5. The rows of teeth 29 and 30 serve for feeding the tobacco downward and distributing itv into a loose roll at the base of the carding-cylinders. The cardclothing may be omitted and earding teeth and pins applied directly to the surface of thev outer case and the inner revolving cylinder, and I wish it understood that my invention is not limited to the card-clothing, though I have found such clothing, as above described,

' tributing and forming disk 12 is made of smaller diameter than the outer carding-cyl-y inder 1 and ring 2, and is provided at the bottom with a circular horizontal flange3l, forming the bottom of the circular channel C, and projecting below thegrooved compressing-I disk 39. Adjacent to flange 31 in disk 12 there is cuta deep annular forming-groove 32, and a' projecting sharp cutting-lip forms the upper edge of the groove and iits over the upper cutting-edge of wheel 39, as indi cated in Figs. 5 and 7. In order to form the sharp cutting-lip 33, a sharp inclined groove 34 is cut into the disk 12 and serves, also, for receiving the inner edge of the bridge-plate 3S. The disk 12 is provided in its periphery above groove 34 with a circle of long distributing-teeth 35, preferably curved downward and backward into the circular channel C. The carding-cylinder 6, secured to the inner shaft S, is geared to travel two or three times as fast as the distributing and forming disk 2, so that as the stock is fed downward and distributed by teeth 30 itis held within the channel C bythe circle of teeth 35, which also aid in revolving the stock in making a uniform loose rolll and also for feeding such roll forward at the proper speed to be formedinto a rod. For the purpose of still further distributing the stock and leveling it in the roll formed in channel C, a circular band 36, provided with a serrated lower edge, is connected by`distance-pieces and screws37, Figs. 4 and 7, to the periphery of disk 12, and is of a suitable width to travel over the top of the bridgeplate 38. For the purpose of regulating the amount of tobacco-stock fed into the circular opening. between the two grooved formingdisks, I provide a bridge-plate 38 of curved form, as shown in Fig. 7, arranged above the groovedcompressing-wheel 39, and projecting at its inner edge into the groove 34 of disk 12. A portion is cut away from the lower edge of band 2, forming a wide notch or recess for inserting the bridge-plate 3S and for receiving the inwardly-projecting edge ot' the compressing-disk 39, as shown in Figs. 4 and 5.

The compressing-disk 39 is provided with a groove in its periphery and with sharp cutting-edges for operating, in conjunction with the cutting-lip 33 and the forming-groove 32 in disk l2, to shear off the tobacco-stock as it is fed forward in the ,form of a loose roll and compressed into a filler-rod by passage between the two grooved disks, and such disk 39 is mounted upon an adjustable stud-pin 40, set into aslotted bracket-arm 41,which pin 40 is provided with a nut below the bracketarm for holding it in place. The stud-pin 40 may have a downwardly-extending shaft 40, provided at its lower en d with a pulley 42, which is connected by a twisted belt 43 with the pulley 44 on the hollow shaft 14, as shown in Fig. 4, for positively turning the grooved compressing-disk 39, if desired. Ihave found, however, in practice that the grooved disk 39 may be successfully turned by frictional contact with the tobacco-stock in the groove 32 of disk 12. The stud-pin 40 is` flattened on its sides which are in contact with the slotted arm 4l to prevent it from turning, and by means of the nut below the slotted arm the disk 39 may be slightly adjusted out or in for varying the size of the filler-rod.

The slotted trough or folding-channel 45 is arranged longitudinally on top of the divided table T T and extends at its front end below the junction of the grooved compressing and forming disks, -as shown in Figs. 4, 5,

and 7. The channel is composed of the two adjustable guide-bars 45n and 45, (illustrated IOO IIO

in longitudinal plan View in Fig. 14 and by f in perspective View, Fig. 29.

from their front ends to about their middle portions, as shown in Fig. 14. As shown 1n Figs 15, 1G, 17, and 1S, these guard-flanges are gradually inclined downward from nearly a horizontal position at their front end, as shown in Fig. 15, to nearly avertical position atI their rear ends, as shown in Fig. 1S, and thereby aid in curving the belt and paper ribbon from a horizontal positioninto a U shape, as shown in Figs. 20 and 21. By reference to the above figures it will also be seen that the inner walls of theguide-bars rise from a nearlyhorizontal or slightly-inclined surface at their front ends to a nearly-vertical surface at their rear ends, so as to aid in curving the belt and ribbon and forming a U-shaped channel. It will therefore be seen that the channel is broad and concave at the front end, and is tapered so as to be deep and comparatively narrow at the rear end of the guard-flanges, as indicated in Figs. 1S and 19. In Fig. 14 the tapering Walls of the channel 45 are covered by the guard-flanges 45C, but are indicated by the longitudinal dotted lines. The different slopes and inclinations of the inner walls of the guide-bars are also clearlyshown in Figs. l5 to 19, inclusive. Beyond the rear end of the guard-flanges 45C the walls of the channel are substantially parallel to the rear end thereof. The slot formed between the inner lower edges of the guide-bars 45 and 45b is for permitting the passage of the carrier-belt 40n within the channel, while the power-belt 46, to which it is longitudinally connected, travels below the channel. The power-belt 4G is made thick and strong, preferably of leather or similar material, and is arranged to travel in the longitudinal passage-way between the table-bars T T', as shown in Figs. 4 and 5, and is preferably provided with a central longitudinal groove in its lower surface for bearing upon the central longitudinal rib of the bed or bar 47.

The carrier-belt 4G is preferably made of enameled leather, which is considerably lighter than the power-belt, and is connected to the power-belt by a longitudinal line of stitches or other connecting devices, as shown The power-belt, with its attached carrier-belt, passes at the front end of the machine over pulley 50, and at the rear end of the machine over the large driving-wheel 72, by means of which it is caused to travel and pull the carrier-belt,

, which carries the paper ribbon and filler-rod through the folding-chann el. The belt-p ullcy 50 and the paper-ribbon pulley 51 are mounted in suitable journal-boxes upon the adjustable bridge-plate 49, mounted upon the front end of the divided frame V, as shown in Figs. 1 and 2, and such bridge-plate 49 is made adj ustable by means of a screw arranged within the frame, but not herein shown, for the pur-' poseof tightening the belt. The paper' ribbon 52 is taken from a reel 53, suitably journaled by its axle in the bar or bracket 54,se cured to the frame and legs of the machine,

as shown in Fig. 1, and is applied to the carrier-belt 4G, in which it is wrapped around the filler-rod.

A pair of extractors or stripper-guides 48, having tapered ends and grooved inner surfaces, are secured to the guide-bars 45 and 451 and extend tangentially into the grooves of forming and compressing disks 12 and 39 for detach'ing the tobacco rod from such grooves and guiding it onto the carrier-belt and'paper ribbon in the folding-channel.

For the purpose of pressing down the tobacco `of the filler-rod away from the standing edges of the paper in the channel, I provide a tapering concave presser-linger 55, Figs. 2, 9, l0, 20, and 2l, which has attached to its large front end a cross-bar 5G, by means o f which such fingeris secured to the guide-bars 45 and 45h, so as to lie within the foldingchannel just beyond the rear ends of the guide-flanges 45C. The front end of the finger is made broadest and is slightly curved upward,as shown in Fig. 9, and its under surface is made concave, as shown in Fig. 10, to assist in shaping the rod just previous to application of the wrapper. At about the middle of the finger 55 raised bridge 57 is screwed to the side bars and is provided with an adjusting-screw 58, which engages, by means of a small head or disk at its lower end, with a dovetailed groove 55, attached to the top of finger 55, by means of which the finger may be adjusted up or down for regulating the pressure upon the tobacco-rod. The disk at the lower end of the screw forms Va swiveled joint with the dovetail groove 55, as clearly shown in Figs. 9 and 10.

Adjacent to the rearcnd of linger 55 Ipro- 4vide a curved belt dellector or curver 59. attached to the inside of the guide-bar 45b just below the paste-wheel GO, as shown in Figs. 2 and 12, and such deflector serves to turn over one edge of the carrier-belt and paper wrapper below the paste-wheel, while the opposite edge, which is to receive the paste, is left standing against the opposite vertical wall of the channel for application of paste by the revolving paste-wheel GO, as shown in Fig. 12.

The wheel GO is secu red to the top of the short vertical shaft 6l, which has secured to it a beveled spur-wheel 62, meshing with a sim ilar spur-wheel G3, fixed upon the horizontal transverse shaft 64, which is suitably journaled in an adjustable carriage 66, arranged in the frame of the machine, and is provided at its opposite end witha grooved belt-pulley ('55. The carriage 6G has also connected to it the paste-cylinder 73 and is adjusted laterally by means of a screw U7. The paste-wheel and its gearing are operated by a round hand 68, passed over pulley and arranged in a groove formed in the periphery of the gearwheel (59, Figs. 1 and 2, which is mounted upon the transverse shaft and is turned by the beveled pinion 71, fixed upon the driving-shaft 2l. The large belt-wheel 72, on

which is placed the power-belt, is also fixed ICI iol

IIt

trg

upon the same transverse shaft 70, which is supported by hangers, (not shown,) but extending downward from the frame \V.

- The horizontal paste-cylinder 7 3 is preferably arranged parallel with the frame of the machine to which it is connected and is provided near its front end with a longitudinal slot 73 for receiving the edge of the pastewheel 60. The paste-wheel and its operatinggearing and the paste-cylinder being connected to the carriage 66, the whole may be adjusted laterally by means of -the screw -67 for operating in conjunction with the guidebars n and 45h when it is desired to vary the size of the cigarette.

An adjustable slotted scraper 74, Fig. 13, is connected with the inner side of the pastecylinder and the two. prongs thereof are arranged to embrace the paste-wheel for removing therefrom superfious paste, so that ent end a weight- 79 for forcing the piston forwardinto the paste-cylinder, and thereby keeping the paste in contact with the revolving paste-Wheel.

Just beyond the deiiector 59 I arrange in the folding-channel a separating-finger S0,

. and connect it to the side bar 452L by a shank 81, Figs. 2 and 11. 'This finger 80l performs the important ofice of raising and separating the edge of the belt which has been turned down by the deilector 59, while at the saine time it holds down against the tobacco-rod the turned-down edge of the paper, thus sep- Yarating one from the other.

Beyond the separating-finger 80 I arrange in the folding-channel a curved detlector 82, attached to the inside of bar 45a, for curving and turning down the left-hand edge of the belt and the pasted edge of the paper, so as to lap such pasted edge upon the previouslyturned-down edge of paper, and cause it be sealed thereon, thus completely inclosing the filler-rod and forming the finished cigaretterod ready to be cut into short lengths. The cigarette-rod is carried forward by the carrier-belt and the power-belt 46, passing over The reciprocating carriage 83, which supports the cutting-disk, is mounted upon the longitudinal guide- rods 84 and 85, fixed in the laterally-projecting bracket- arms 86 and 87, bolted to the frame WV of the machine, as shown in Figs. 26 and 27. A curved arm 8S is secured to carriage 83 and supports at its outer end the cigarette trough or holder 89, which is made tapering and concave, as shown in Fig. 28. It is preferably made in two sections having a transverse slot between them and connected by a downwardly-curved link 89, which transverse slot is'provided for the passage of the cutting-disk 96. The 'edge of one section of the trough at the transverse slot acts as one edge of a shear, against which there works the other edge of the shear composed of the vibrating cutting-disk 9G. The mechanism for revolving the cuttingdisk and giving it a vibrating motion is mounted on a rock-shaft 92, supported in journal-boxes 90a and 91a at the top of the standards 90 and 91, which are secured at their lower ends to the carriage 83, as clearly shown in Figs. 25, 26, and 27. arms 93 and 94 nearly at right angles one to the other, the arm 93 extending downward through the carriage and having at its lower end a set-,screw 93a, which bears upon the cam 107, and the lever 94 extending horizontally and having at its outer end a short journal-bearing 94%. A short shaft is arranged in the bearing 94 and carries at one end the grooved pulley 95 and at the other end the cutting disk or blade96. It will be seen that since the lower end of lever-arm 93 bears upon cam 107 the cutting-disk will v-be given an up-and-down vi-brating motion through the medium of rock-shaft 92 and lever-arm To shaft 92 are secured two lever- IOO 94, so as to alternately approach and recede from the holder-trough 89 for cutting the cigarette-rod into short lengths.

For the purpose of revolving the cuttingdisk I provide the large and small pulleys 97 and 98, connected to the same hub, which is mounted on the rock-shaft 92, and I connect pulley 97 to pulley 95 by a band 99 and connect pulley 98 by a band 100 with pulley'lOS, ixed upon the driving-shaft 101 below the reciprocating carriage. The driving-'shaft 101 is mounted in journal-boxes 102 and 103 upon the ends of horizontal arms secured to the frame WV, and has secured to it the pinion 104, which meshes with the spur-wheel 22 von shaft 21, Fig. 1. A grooved cam 105 is attached to shaft 101 and is provided in its periphery with a cam-groove m, with which there engages a downwardly-projecting arm 106,'having at its lower end the roller n, working in the camgroove. The arn1'106 is rigidly secured to the reciprocating carriage S3, and by means of such arm and the cam 105 the carriage is given a reciprocating motion. The guide- rods 84 and 85 are provided at their ends with coiled springs sbetween the 'carriage and the bracket-arms S6 and 87 for assisting the motion of ,the carriage as it isthrown back and forth by the cam 105. The cam 107, pulley 108, andthe grooved hub 100 are preferably all cast together and are connected with shaft 101 by lneans of a spline joint or feather o, so that they may be reciprocated upon such shaft, while at the same time they are made to turn with it.

In order to give the cam and pulley rcciprocating motion with the carriage 83, l attach to the under side of such carriage the forked arm 110, the prongs at the lower end of which engage with the grooved hub 109, as shown in Fig. 25. By means of this construction the lever-arm 93, cam 107, pulley 98, and pulley 108 are maintained in proper` alignment and relation to each other as the carriage 83 is reciprocated. By means of the reciprocating carriage and the operating mechanism the cutting-disk is moved forward with the cigarette-rod during the instant required for cutting through such rod, thereby preventingl any cramping or bending of the same. By means of the vibrating motion given to the cutting-disk--that is, a motion downward and through the traveling, cigarette1od-l avoid the objectionable deflection of the rod in order to bring it in contact with the cutting-edge of the disk, as heretofore proposed, and thus avoid wrinkling or breaking the paper wrapper and the tendency to open the seam at the pasted edges, which re-` sult from moving the rod toward and from the cutting-disk, as heretofore proposed.

The operation of the machine is very simple and it can be successfully managed by one attendant. MThe belt is shifted on the xed pulley of the power-shaft 23, and the clutch 20 upon the shaft 2l is moved by the lever 20 to engage with the sleeve-shaft carrying the gear-wheels 17 and 18, by which all parts of the machine are set in motion. The fine-cut tobacco-stock is fed into a hopper set on the outer carding-cylinder 1, and thus falls down into the spiral grooves of the carding-eylinder 6, by which it is fed into the space between the carding cylinders, and thus opened and drawn apart into a loose thin jacket and is gradually fed downward and distributed by the circle of teeth 30 into the circular channel C.

Since the carding-eylinder revolves two or three times as fast as the grooved formingdisk 12, the circle of teeth 35 on the latter disk serve to hold the roll of stock in channel C, and such teeth, together with the serrated band 3G, serve to regulate the stock and to level it into a practically uniform roll, also to carry forward such roll into the opening `formed by the junction of the grooves in the distributing and forming disk 12 and the forming and compressing disk 39. The overlapping cutting-edge 33 of disk 12 and the eutting-edge of disk 39 shear off the required amount to form the ller-rod, which is compressed and passed through the opening between the grooves of the two disks, while the excess of stock, whichis fed forward in the channel, is conducted above the bridge 38 by means of the teeth 35 and the serrated band 3G. As the stock is sheared off by the cut tin g-edges of disks 12 and 39 and is passed through the opening formed by the grooves it is compressed into a filler-rod, and such rod is detached or stripped out of the grooves by the tangential stripperguides 48, and guided thereby directly upon the paper ribbon 52, traveling with the filler-carryingbeltt in the folding-channel 45. As the filler-rod passes Aforward in the channel it is smoothed down and somewhat compressed by the presserfinger 55, so as to leave the standing edges of the wrapper and belt free from fibers in a most favorable condition for being inclosed iu the wrapper. As .the Iiller-rod, paper wrapper, and carrying-belt pass beyond the rear end of the presser-linger the right-hand ed'ge of the paper and belt are turned over and down upon the filler by means of the curved deflector 50, while the paste-wheel 60, above such defleetor, applies paste to the opposite standing edge of the paper. The pastewheel is preferably tilted downward toward the rear end of the machine and is caused to revolve in a direction opposite to the travel of the paper and carrier-belt, whereby the paper is better held in a smooth vertical position. After leaving the deflector 5!) and paste-wheel the turned-down edges of the belt and paper are separated one from the other by means of the separating-linger 80, which raises the edge of the belt into a standing position, while it holds down the edge of the paper upon the filler. The belt is slitticiently resilient and springy to readily unfold and return to a standing position in the channel, while the edge of the paper passes under the separatingfinger 80. The lefthand edge of the wrapper and belt are turned over by the deflector 82, thereby lapping the opposite edge of the paper upon the previously-tnrned-down edge and sealing the wrapper around the filler, thus completing the formation of the cigarette-rod. The completed rod is carried forward by the belt and conducted into the helder-trough 89, in which it is subjected to the action of the cutter-disk 06, working' through the transverse slot in such trough, as before explained. Duringthedownward stroke of the vibrating lever-arn1 94 the disk 9G is caused to traverse the cigaretterod and project into the transverse slot of trough 80, and at the same time the reciprocating carriage 823 is moved forward, so that during the instant when the cutting-disk passes down through the cigarette-rod it also moves forward in line with such rod, so that there is no back-pressure on the rod, and so that no injury result-s to it from cramping or bending and no trouble arises from bursting of the wrapper and the freshly-sealed edges. As a result Iobtain a well-formed, well-scaled, and smooth cigarette.
